BRAKE-BEAM GUIDE.

T 0, all. to hem it, may concern:

Be. it' known thZLllI EDWIN G. Bu'ssn, a citizen of theUnited States, residing at Chicago, Illinois,v have invented acertain new and useful Improvement in Brake- Beam Guides, of which the following is a.

specification, such as. will enable others skilled in .the art to which it; appertai nsl to make and. use; the a same.

My invention is; an: improvement; in. railroad ,rollingstock and relates particularly to thirdrandzzfourth point supports and guiding: means-for brake beams. 4

The object of my inventionis toprovide tliird rand fourth ipointsupports which guide the applicationr'ofi the brake shoe tothe wheel aswell as performing the ordinary functionl of: acting; as safety. means to preven,t:,t-he dropping of. thebrake beam asse-m-.

bly' on I, the. rails. Also :to: provide acombination third and fourth point support and,

guidee-member yvhich willv permit the reversali'of the brake; shoe when. it becomes-- Worn.

bringing. the. end immediately under and in a. plane parallel to-the inclined portion. 7

is a. slot in the bend; between. the two. par;;

allel portions. and .8.. is a, second slot opposite slot 7- in the upper. end. ofth e vertically dise posed portion. The F function of these, slots.

In operation, when .thebrakes are applied,

endof bolt-11 holds spring 12- and thebolt the guide member9 slides forwardly through slots 7 and 8 untilthedifference in the arc of. movement of brake beam 2Exvhich'pivots from the brake hanger support, (not-shown) causes theguide to become wedgedbetween the parallel guiding portions of;v bracket strap 6. If the necessary movement is notv yet completed thebrake beam. may slide forwardly; relative to strap 10 and the for- I Ward 1 portion. ofstrap 9, thereby compress: ing' spring 13 The: forward movement. of.

the brake beam relative to the guide meme her is .limitedbythe spr-ing 13 and bolt 11 Y .andby the clearance,betweentheb-rake beam and the guide members. These parts would eventually Wedge due to the twisting; ofthe brake-beam. When the brakes are released the parts resumetheir normal positions, the springs Band 13 recentering brake beam Qinrelation to straps-9 and 10 andthe back.

strap 9 in'thebrazcket G. At. alltimes the assembly prevents any marked u Ward.- or downward movement ofthe bra {e beam.

With this-typeof guide and the. flexibility:

of movement which. it permits,,it is Wholly practical to reverse a brake-'slloe in-case one side is unduly WOI'IL. w i

In Figure 3 a modification isshown asteelstrap 15' is bent vertically upwardly.- from under spr-ingplank. 1' andthenback over the spring plank slightlv inclined. to

in vvh ich.

thehorizontal. A=slot16iscutjustbelowtlie upper bend. A steelstrap 17 isthe. guide. member in this form-and is ,passed through: slot 16'. It extends outwardly from slot 16.

and is. then curved. back, under itself, j then downwardly then forwardly. to enclose. brake beam 2,. and! a. .pair of coil springs 15. and 19 which are mounted. one abovethe:

other between the back of brake beam 2 and the forward side of the vertically disposed portion of strap 17. Bolts and 21 are passed through brake beam 2and strap 17 to guide springs 20 and 21 and hold them in place. Nuts 22 and 23lock bolts 20 and 21 in place.

The operation of this form is very similar to the other, the principal difference being that a practically unlimited upwardtwist or movement of the brake head is permitted since there is only a single guiding surface in the bracket 15. A downward twist or movement is limited the same as in the preferred form and restoration of the position of the parts being similarly effected.

In Figure 5 the bracket 2st and guide 25 extend downwardly from the spring plank and beam, respectively, but the relative position of the parts and their functions are practically the same. In this construction the lower face of the spring plank serves as one of the guiding surfaces for the beam member 25. here other truck equipment or other reasons prevent the preferred mounting of the bracket and guide, this arrangement may be substituted.

In each of these forms there is present a bracket member, a guide member slidable therein, and a yielding moimting of the beam on the guide member. The bolt and nut provide means for adjusting the resistance of the springs. While I prefer to make the bracket and guide rigid elements, it is obvious that they could be made of spring material to increase the flexibility of the devices.

Other modifications of my invention may be made without departing from the scope thereof as expressed infthe appended claims.

I claim:

1. In a car truck, a fixed member, a brake beam, a guide element yieldingly connected to said beam, and a sliding connection be tween said guide element and said fixed member.

2. In combination, a spring plank, a brake beam, a guide element yieldingly secured to said beam and extending over said spring plank,and a sliding connection between said element and said brake beam.
